Douluo See You For a Long Time

Although Chengying has already been tempted, knowledge is still a very precious thing in this era, so he has to be a little more reserved.

"You are alone, what can you do at sea? Sailing is not something that one person can do. I didn't see that I brought these 800 sailors to start this giant ship. If you really want to find your loved ones, you might as well ask me for help." You search the sea a few times."

"But I..." Bo Lan didn't really lose his parents in the first place, and it was hard to refute because his feelings were not ready for a while.

"Teacher, don't you always say that teaching a man how to fish is worse than giving him a fish? How can you replace Bo Lan in sailing, and teach her the skills of long-distance sailing?" Cheng Ying looked at Tang Chen who stood up to help, and couldn't help it. Holding your forehead with one hand, you wonder where are you from?

"You have to think about it. Knowledge is priceless. It's impossible to pass it on to you for nothing. Of course, it's a different matter if you formally become a teacher. Otherwise, I can only teach you some superficial things." Cheng Ying I think that in this way, it should be possible to take in another apprentice.

Unexpectedly, Bo Lan fell into hesitation, and said after a long while: "Sorry, I'm afraid I can't take you as my teacher."

"You already have a master?" Cheng Ying was puzzled, she didn't look like she had a master!

"No, it's just because of some reasons that it's not convenient to be a teacher. I can treat you like a teacher, but I'm afraid I can't be a teacher..." Seeing that Bo Lan's tangled expression didn't seem fake, Chengying couldn't help but raise his eyebrows.

From all aspects, Bo Lan has no reason to refuse to be a teacher, unless... it is because her identity is not suitable. Reminiscent of the original book, she has been alone on Sea God Island for nearly a hundred years, just to wait for the successor of the god, and finally returned to the school. To complete the inheritance of the Sea God by sacrificing himself, I am afraid that his identity is very special.

"Forget it, if you really don't want to be a teacher, that's fine. For your sincerity, I will teach you anything I can tell you." Chengying recalled Bo Saixi's relationship with Tang Chen and Qian Daoliu in the original book. He said that he would only be with the one who became a god. Now that I think about it, I am afraid it is not simple just to reject Qian Daoliu. It is very likely that the necessary condition for marrying this girl is to become a god.

Bo Lan also heaved a sigh of relief when she heard the words, she was naturally Bo Saixi, as a soul master who was born with the Martial Soul of the Sea God, she was bound to the god since she was born, and all the soul masters on Sea God Island got the god According to the decree, the Sea God designated her as a saint, a soul master dedicated to serving the Sea God.

For a race that has believed in the Sea God for generations, this is undoubtedly a supreme honor, and since it is natural that a saint who serves the Sea God cannot be married, the teacher should not even think about it, otherwise, as a teacher, wouldn't he be on the same level as the Sea God .

Naturally, Bo Saixi, who became a saint, gained a respected status on Sea God Island. She was like the uncrowned king of Sea God Island. The only restriction was that she could not leave the place of Sea God's inheritance.

Unfortunately, Bo Saixi is on Sea God's Island. There are very few people who yearn for freedom and want to see the world with their eyes open. The adventurous spirit is the most precious kind of will on the isolated desert island. It happened to the most inappropriate people.

She escaped countless times, but she was either swept back by the sea or captured by the sea spirit beast. Every time she was swallowed by the sea spirit beast and spit out, it was a nightmare experience, as if this was the sea god punishing her The general escape.

This time, I thought I was going to be captured again, but I didn't want to run into the World's End passing by. The sea soul beast that captured her was killed directly. With such a huge ship, it was simply the best chance to escape from Sea God Island.

But she is very clear that the power of the gods cannot be resisted by humans. Although the giant ship is strong, it is unrealistic to take her away under the obstruction of the gods. The result of forcibly taking her away can only be Buried in the sea.

She didn't want to implicate innocent people because of her own reasons. She just wanted to learn as much as possible about traveling across the ocean before she was caught, so that she wouldn't be washed back by the current in the ocean because she didn't know the direction.

Naturally, she couldn't worship Chengying as her teacher, because that would only harm him. No one knew what kind of character Sea God was, and if she was too narrow-minded, she would definitely not allow her saint to have a teacher.

It's just a fan of the authorities, she has never thought about why she has fled so many times and nothing happened...

In fact, Chengying almost guessed the truth, so he also planned to teach Poseidon as much as possible about sailing. He believed that even if he couldn't kidnap her, she would rely on her own ability to escape from Sea God Island after learning these things. come out.

Then……

Then Bo Saixi realized what is called sea tactics and what is called cramming education. With so few people on Sea God Island, it would be idiotic to want to manufacture a qualified nautical clock.

If you only know the latitude at sea, you are just drifting around blindly. If you don't have a clock to determine the longitude, you can only rely on the stars in the sky.

If you are on Earth, you can see Jupiter or Jupiter’s satellites. If you are in Douluo, you have to re-observe the star map.

Chengying hasn't measured the data in this area yet, so I have to teach Bo Saixi how to confirm the time by observing the stars, and then let her sum it up by herself.

But the problems here are complicated, you need to learn the law of universal gravitation! To calculate the movement of the stars, you must learn the conic section! Like proficiency in using a sextant to observe stars, the most basic analytic geometry needs to be learned!

Not to mention the more complicated ones, conic sections and analytic geometry, the difficulty is simply terrifying for people who have no foundation at all. Chengying actually wants to say that if you want to calculate accurately, you need to learn calculus, but after thinking about it He still didn't teach it. To be serious, he might have to talk about using imaginary numbers to solve cubic equations in one variable. That's a few years of learning, even if Bo Saixi's head is lifted, he can't finish it.

These days, Bo Saixi is also in pain and happiness. Although what Chengying said is difficult and difficult to understand, and is jokingly called the knowledge of the gods by several other students, it has indeed benefited her a lot.

Especially after knowing that the thing under her feet is probably a ball, she has strengthened her determination to go out and have a look. The ground under her feet is so vast, and a circle is 80,000 miles away, let alone Talk about the misty sky.

She may never have the chance to set foot on the sky in her life, but it would be a pity if she missed the ground under her feet.

The diameter of the planet under the feet is 40,000 kilometers, which was measured by Chengying himself with the length of the shadow of the sun. It can be said to be a coincidence, or it can be said to be inevitable, otherwise the parameters such as the acceleration of gravity will definitely change.

On this day, after Chengying explained to Bo Saixi how to use the analytical method to find the tangent of an ellipse, he looked at the dark clouds billowing in the distance, and couldn't help squinting his eyes: "What should come will always come."
